Hoyt was promoted to the major leagues for the first time in September 1979.[3] A relief pitcher when he made the White Sox to stay in 1980, Hoyt was switched to the starting rotation in 1982 and tied a club record by winning his first nine decisions. The record was first set by Lefty Williams in 1917 and equaled by Orval Grove in 1943. Hoyt ended up leading the American League with 19 wins.[4]
The White Sox faltered in 1984, as Hoyt's record fell to 13–18 with a 4.47 ERA. He went from winning the most games in the American League in 1983 to losing the most games the following year.[4]
Following the 1985 season, he was arrested twice within a month (between January and February 1986) on drug-possession charges, checking into a rehabilitation program nine days after the second arrest.[11] This prevented him from playing most of spring training. He pitched through an injury to his rotator cuff rather than risk a surgery that could end his career, and he logged an 8–11 won-loss record with a 5.15 ERA.[4]
Barely a month after the season ended, Hoyt was arrested again for drug possession when he tried to bring 500 pills through the San Ysidro Port of Entry on the U.S.–Mexico border.[4][12] He was sentenced to 45 days in jail on December 16, 1986, and suspended by Commissioner Peter Ueberroth on February 25, 1987. An arbitrator reduced his suspension to sixty days in mid-June and ordered the Padres to reinstate him. Though the Padres still owed Hoyt $3 million under the terms of his contract, the team gave him his unconditional release the following day.[4]
Later career
The White Sox gave him a second chance, signing him after his San Diego release and giving him time to get back into shape. A fourth arrest on drug charges in December 1987 ended his return.[13] He was sentenced to one year in federal prison in January 1988.[14] He began to serve his sentence at Federal Correctional Complex, Allenwood,[15] and was transferred in July to a halfway house in Columbia, South Carolina.[16]
Hoyt's parents divorced when he was six months old, and he was raised by an aunt. Hoyt and his wife, Sylvia, married in 1980. They divorced after the 1985 season.[17] Hoyt and his second wife, Leslie, had two sons and a daughter. [18]
Hoyt died of cancer on November 29, 2021, at the age of 66.[19]
